[0002] Low-energy buried insulated fixed pipe support structure is a type of pipe support structure adapted to buried pipelines. Its core is to provide stable support for the pipeline while reducing energy loss through optimized insulation design. It can also cope with problems such as humidity and corrosion in the buried environment. It is commonly used in buried pipeline systems such as petrochemical and municipal heating systems.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing underground pipe supports lack impact-resistant structures, making them unable to effectively resist stress impacts from soil settlement, creep, and the pipe's own weight in the underground environment, thereby increasing the risks during pipe use.

[0004] To address this, a low-energy-consumption underground insulated fixed pipe support structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a low-energy-consumption underground insulated fixed pipe support structure, which can solve the problem that the existing underground pipeline fixing lacks an impact-resistant structure, which makes it unable to effectively resist the stress impact caused by soil settlement, creep and the pipeline's own weight in the underground environment, thereby increasing the risk of pipeline use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-energy-consumption buried thermal insulation fixed pipe support stable support structure, including a fixed base, a support mechanism welded to the top of the fixed base, and a fixing mechanism welded to the right side of the support mechanism. The support mechanism includes a support plate, four connecting holes, four ground insertion rods, a lower half fixing ring, a connecting plate, and a rotating rod. The support plate is welded to the top of the fixed base, the connecting holes are opened on both sides of the fixed base, the ground insertion rods are welded to the chamfer at the bottom of the fixed base, the lower half fixing ring is welded to the top of the support plate, the connecting plates are welded to both sides in front of the lower half fixing ring, and the rotating rod is rotatably connected between the two connecting plates.

[0007] Preferably, the fixing mechanism includes two rotating blocks, an upper fixing ring, a heat insulation pad, four fixing blocks, a connecting screw hole, and a connecting screw rod, wherein the rotating blocks are rotatably connected to the surface of the rotating rod.

[0008] Preferably, the upper half of the fixing ring is welded to the rear side of the rotating block, and the heat insulation pad is fixedly connected to the inner wall of the lower half of the fixing ring and the inner wall of the upper half of the fixing ring respectively.

[0009] Preferably, the fixing blocks are welded to both sides of the rear side of the upper half fixing ring and both sides of the rear side of the lower half fixing ring, the connecting screw holes are opened on the inner side of the fixing blocks, and the connecting screws are threaded into the inner side of the connecting screw holes.

[0010] Preferably, reinforcing plates are welded to both sides of the top of the fixed base, and the side of the reinforcing plate away from the fixed base is welded to the surface of the support plate.

[0011] Preferably, wear-resistant copper sleeves are fitted at both ends of the rotating rod where they connect to the connecting plate, and the inner wall of the wear-resistant copper sleeves is coated with graphite grease.

[0012] Preferably, a reinforcing ring is welded at the connection between the grounding rod and the fixed base, and the surface of the reinforcing ring is coated with an anti-corrosion coating.

[0013] Preferably, the bottom of the grounding rod is conical, and the bottom of the grounding rod surface is provided with spiral anti-slip texture.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The support structure of this application adopts a triple stabilization structure of base, ground insertion, and reinforcement, which effectively resists the stress impact caused by soil settlement, creep, and the self-weight of the pipeline in the buried environment. The fixed base is fixed in a plane by connecting holes on both sides and anchor bolts. The ground insertion rods at the four chamfered corners at the bottom penetrate into the ground to form a three-dimensional anchor, which prevents the overall displacement of the pipe support. The bottom of the ground insertion rod is designed with a conical structure, which greatly reduces the insertion resistance and facilitates quick installation and positioning. The spiral anti-slip texture on the surface enhances the interlocking friction with the soil and prevents the risk of pull-out due to groundwater erosion or soil frost heave. At the same time, the reinforcing plates on both sides of the top of the fixed base are welded with the support plate and the fixed base to form a triangular stabilization structure, which disperses the vertical pressure transmitted by the support plate and prevents the weld joint from cracking due to stress concentration, further improving the load-bearing capacity of the support structure. 2. The fixing mechanism of this application adopts a closed-loop design with an upper and lower fixing ring, combined with four fixing blocks and connecting screws for symmetrical fastening, achieving all-round fixing of the pipeline. The upper fixing ring is rotatably connected to the rotating rod of the support mechanism through a rotating block, which can be flexibly opened and closed around the rotating rod, facilitating rapid fixing after the pipeline is hoisted into place. During fixing, the upper and lower fixing rings are connected, and the connecting screws and the connecting screw holes on the fixing blocks are threaded together to form a uniform clamping force, preventing radial displacement or axial movement of the pipeline. This is especially suitable for buried pipelines transporting high-pressure media. The heat insulation pad, through its tight cooperation with the fixing ring, constructs a highly efficient heat insulation barrier. The heat insulation pad is fixedly connected to the inner walls of the upper and lower fixing rings, and is tightly attached to the pipeline surface, effectively blocking the heat exchange between the medium inside the pipeline and the external soil, reducing heat or cold loss, and lowering energy consumption during transportation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A low-energy-consumption underground thermal insulation fixed pipe support structure includes a fixed base 1, a support mechanism 2 welded to the top of the fixed base 1, and a fixed mechanism 3 welded to the right side of the support mechanism 2. The support mechanism 2 includes a support plate 21, four connecting holes 22, four ground insertion rods 23, a lower half fixing ring 24, a connecting plate 25, and a rotating rod 26. The support plate 21 is welded to the top of the fixed base 1, the connecting holes 22 are opened on both sides of the fixed base 1, the ground insertion rods 23 are welded to the chamfer at the bottom of the fixed base 1, the lower half fixing ring 24 is welded to the top of the support plate 21, the connecting plates 25 are welded to both sides in front of the lower half fixing ring 24, and the rotating rod 26 is rotatably connected between the two connecting plates 25.

[0019] In this embodiment: the fixed base 1 supports and limits the support mechanism 2. The support plate 21 is vertically welded to the top of the fixed base 1 to form a vertical support frame. The connecting hole 22 can be used with anchor bolts to form a rigid connection between the fixed base 1 and the underground pre-embedded structure, further improving the pipe support's resistance to displacement and preventing displacement due to soil creep or groundwater erosion. The ground-inserting rod 23 penetrates deep into the underground soil, forming a three-dimensional fixing structure with the planar support of the fixed base 1, which greatly enhances the pipe support's resistance to overturning and pull-out, effectively coping with geological changes such as soil frost heave and settlement. The lower half of the fixing ring 24... Its arc-shaped inner wall fits against the outer surface of the pipe, providing a large area of ​​support contact for the pipe and preventing deformation of the pipe due to local stress. At the same time, the lower half of the fixing ring 24 is rigidly connected to the support plate 21 by welding, ensuring the stable transmission of the supporting force. The connecting plate 25 welded to its front side provides an installation base for the rotating rod 26. The connecting plate 25 can support and limit the rotating rod 26. The rotating rod 26 provides a rotation axis for the rotating block 31, allowing the upper half of the fixing ring 32 to rotate flexibly around it. This facilitates quick closure and fixation after the pipe is hoisted into place, as well as convenient opening during later maintenance, greatly improving installation and maintenance efficiency.

[0020] Specifically, such as Figure 3 As shown, the fixing mechanism 3 includes two rotating blocks 31, an upper fixing ring 32, a heat insulation pad 33, four fixing blocks 34, a connecting screw hole 35, and a connecting screw 36. The rotating blocks 31 are rotatably connected to the surface of the rotating rod 26.

[0021] Specifically, such as Figure 3 As shown, the upper half-fixed ring 32 is welded to the rear side of the rotating block 31, and the heat insulation pad 33 is fixedly connected to the inner wall of the lower half-fixed ring 24 and the inner wall of the upper half-fixed ring 32 respectively.

[0022] Specifically, such as Figure 3 As shown, the fixing blocks 34 are welded to both sides of the rear side of the upper half fixing ring 32 and both sides of the rear side of the lower half fixing ring 24 respectively. The connecting screw holes 35 are opened on the inner side of the fixing blocks 34, and the connecting screws 36 are threaded into the inner side of the connecting screw holes 35.

[0023] In this embodiment: the rotating block 31 can drive the upper half of the fixed ring 32 to rotate. The arc size of the upper half of the fixed ring 32 matches the pipe. After closing, it and the lower half of the fixed ring 24 together form a full-range clamping of the pipe, effectively limiting the radial displacement and axial movement of the pipe. The heat insulation pad 33 is made of low thermal conductivity material and fits tightly against the pipe surface and the inner wall of the fixed ring, effectively blocking the heat exchange between the medium in the pipe and the external soil, greatly reducing heat or cold loss and reducing the energy consumption of the conveying system. At the same time, the heat insulation pad 33 has a certain elasticity, which can absorb the displacement caused by the thermal expansion and contraction of the pipe, avoid the wear caused by direct friction between the pipe and the metal fixed ring, and buffer the impact force transmitted from the pipe vibration to the fixed ring, realizing the dual functions of heat insulation and protection. The fixed block 34 can support and limit the connecting screw hole 35. The connecting screw hole 35 matches the connecting screw 36 to ensure that the two form a tight threaded connection to prevent loosening due to vibration. The connecting screw 36 can lock and unlock the upper and lower fixed blocks 34 by rotation. The operation is simple and efficient, and it is convenient for on-site installation and later maintenance.

[0024] Specifically, such as Figure 4 As shown, reinforcing plates 4 are welded to both sides of the top of the fixed base 1, and the side of the reinforcing plate 4 away from the fixed base 1 is welded to the surface of the support plate 21.

[0025] Specifically, such as Figure 5 As shown, wear-resistant copper sleeves 5 are fitted at both ends of the rotating rod 26 and the connection point of the connecting plate 25, and the inner wall of the wear-resistant copper sleeves 5 is coated with graphite grease.

[0026] In this embodiment: by setting the reinforcing plate 4, a stable triangular support system is formed with the fixed base 1 and the support plate 21, which can effectively disperse the vertical load transmitted by the support plate 21 and avoid cracking of the welded joint between the support plate 21 and the fixed base 1 due to stress concentration. By setting the wear-resistant copper sleeve 5, it has good wear resistance and lubricity, which can reduce the mechanical wear between the rotating rod 26 and the connecting plate 25, reduce the rotational friction resistance, and ensure the smooth opening and closing of the fixed mechanism 3. By setting the graphite grease, long-term lubrication protection is provided, further reducing the wear rate and ensuring that the rotating joint maintains a flexible and reliable working state for a long time.

[0027] Specifically, such as Figure 4 As shown, a reinforcing ring 6 is welded at the connection between the grounding rod 23 and the fixed base 1, and the surface of the reinforcing ring 6 is coated with anti-corrosion paint.

[0028] Specifically, such as Figure 2 As shown, the bottom of the grounding rod 23 is conical, and the bottom of the surface of the grounding rod 23 is provided with spiral anti-slip texture.

[0029] In this embodiment: by setting the reinforcing ring 6, the welding contact area between the ground-inserting pole 23 and the fixed base 1 is increased, the root stress of the ground-inserting pole 23 under stress is dispersed, and cracks or breaks are prevented at the weld due to repeated stress, thus improving the anchoring reliability of the ground-inserting pole 23. By setting the anti-corrosion coating, the corrosion of the weld joint by underground corrosive media can be resisted, preventing rust from spreading from the root and extending the service life of the connection structure between the ground-inserting pole 23 and the fixed base 1. By setting the bottom of the ground-inserting pole 23 to be conical, the resistance to insertion into the soil is reduced, making it easier to install quickly. By setting the spiral anti-slip texture, the interlocking friction with the soil is enhanced, further improving the anchoring stability and preventing the ground-inserting pole 23 from loosening or falling out under stress.

[0030] Working Principle: First, during construction, the operator places the fixed base 1 at the pre-installed position of the buried pipeline. The insertion rod 23, with its conical bottom, can easily insert into the underground soil, significantly reducing installation resistance. The spiral anti-slip texture on the bottom of the insertion rod 23 tightly engages with the soil during insertion, initially forming an anti-pull-out anchoring effect. Then, the operator inserts anchor bolts through the connecting holes 22 on both sides of the fixed base 1, securing the fixed base 1 to the underground pre-buried structure. Combined with the three-dimensional anchoring of the insertion rod 23, this effectively resists the influence of external forces such as soil creep and groundwater erosion, preventing the pipe support from shifting or sinking. Next, the operator places the pipeline on the inner wall of the lower half of the fixing ring 24, ensuring the pipeline surface contacts the surface of the heat insulation pad 33. Then, the operator rotates the rotating block 31 around the rotating rod 26. The rotating block 31 drives the upper half of the fixing ring 32 to rotate synchronously, covering the top of the pipeline and forming a complete structure with the lower half of the fixing ring 24. The ring-shaped covering structure ensures that the heat insulation pads 33 on the inner walls of the upper half-fixing ring 32 and the lower half-fixing ring 24 are tightly attached to the pipe surface. This not only blocks the heat exchange between the medium inside the pipe and the external soil through the low thermal conductivity material, but also buffers the direct contact between the pipe and the metal ring with its own elasticity, thus achieving the initial function of heat insulation and protection. After the upper half-fixing ring 32 and the lower half-fixing ring 24 are connected, the fixing blocks 34 welded to their rear sides are completely aligned, and the connecting screw holes 35 opened on their inner sides form a coaxial channel. At this time, the operator screws the connecting screw 36 into the connecting screw hole 35. The tightening force generated by the threaded engagement makes the upper and lower fixing blocks 34 fit tightly together, causing the upper half-fixing ring 32 and the lower half-fixing ring 24 to form a uniform clamping force on the pipe, effectively limiting the radial displacement and axial movement of the pipe. Finally, the tightly fitted rings make the heat insulation pads 33 seamlessly contact the pipe surface, completely blocking the thermal bridge, further improving the low energy consumption effect, and achieving stable pipe fixation and efficient heat insulation.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
